I’m looking for a B2B remote role where I can design production-grade autonomous LLM systems: multi-provider routing, reliable event-driven workflows, and strong observability, while building real product impact.

AI Engineer building production LLM agent systems with multi-provider orchestration and observability.
UkraineWhat I'm looking for
I’m an AI Engineer with 6+ years in software engineering, and the last 2 focused on production LLM systems. I design autonomous LLM agents and turn them into reliable, event-driven products.
I build autonomous LLM agents on LangGraph with durable workflows (PostgreSQL checkpointing) and multi-provider routing across Anthropic Claude, OpenAI, and Google Gemini. I add reliability with retries/fallbacks and improve output quality using LLM-as-a-judge (best-of-N) so the highest-quality result ships automatically.
I take engineering quality seriously: I implement LLM observability with LangSmith tracing, including tool calls and token usage to debug failures fast. I also deliver semantic search and deduplication with pgvector, backed by an embedding microservice (sentence-transformers, ONNX).
Recently, I’ve been building an end-to-end autonomous Solana crypto AI agent—from on-chain data ingestion and LLM workflows to a Next.js admin panel. My strengths are system design, event-driven architecture, and cloud deployment on AWS, GCP, and Azure.
